Tips & Notes

Pro tips

Use fresh lime juice, not bottled — it brightens the coffee notes and prevents a flat, chemical taste.
Chill your glass beforehand for a smoother mouthfeel without over-dilution.
Stir gently with ice for 10–15 seconds to chill and marry flavors without aerating.

Substitutions

Old Mr. Boston Coffee Flavored Brandy → Kahlúa or other coffee liqueur (sweeter; adjust ratios to taste)
Fresh lime juice → lemon juice (sharper, less aromatic; use 2/5 oz)
Old Mr. Boston Tequila → any 100% agave blanco tequila (flavor profile may vary)

Common Questions

Can I make this cocktail without coffee brandy?

Yes. Substitute with coffee liqueur (Kahlúa), cold brew concentrate, or skip it entirely for a lime-forward tequila sour, though the coffee character will be lost or altered.

Should this be served straight up or on the rocks?

The recipe doesn't specify, but strain into a glass over ice for a longer drink, or serve up in a coupe for a spirit-forward sipper.

How do I juice half a lime properly?

Cut the lime in half, use a manual citrus juicer or reamer, or squeeze by hand over a fine strainer to catch seeds.

Can I batch this for a party?

Yes. Multiply all ingredients by the number of servings, combine in a pitcher, and serve over ice. Add fresh lime juice just before serving for best flavor.
